Thanks for doing this! You can also use mongodb-memory-server for the database operations, see an example in api/models/Role.spec.js

Updated tests to use mongodb-memory-server - it did change behavior a little as it was lowercasing username based on the schema.

can you also add documentation for this and the other PR? https://github.com/LibreChat-AI/librechat.ai

Sure - I had a question about where the doc for additional OIDC config should live. They're not provider specific but it seems all the generic options are documented under keycloak - is that where you want these documented?

Any help to the end of making a generic page is appreciated.

I will push all your changes with the next release cycle.
